Criminals will always get guns. It isn't the availability of guns for legitimate use that is the danger. It is social and economic factors that cause crime and violence.

I agree there are other very relavant factors but from my UK perspective I'd rather not have guns at all. If guns were allowed and there was a chance I had one in the house, I'd feel more threatened, not safer. Why? because IMO that policy would encourage the criminal who intends robbing me to have a gun to protect himself from my gun. It's a downward spiral.

It's different I think in the US where guns have unfortunately been part of the culture for so long.
